This thesis examines Germanys role at the center of the European Monetary Union (EMU). It explores German socio-economic policies and experiences in order to provide a more comprehensive understanding of why the EMU operates with German influence as well as in opposition to it. Historically, Germanys economic experience, from the Weimar Republic to 2013, has been uniquely shaped by its population and the embeddedness of its market place. From this experience, Germany has erected certain...

The scope of this thesis involves various techniques to control the torque of a voltage source inverter-fed induction motor. The three methods investigated here are voltage by frequency, known as scalar control, field-oriented control with and without space vector modulation, and direct torque control. Although all three techniques have been proven effective, each technique possesses its own advantages and disadvantages. In todays engineering world, time and money are saved by utilizing...

The effects of curvature and the resulting centrifugal instabilities on local heat transfer distributions are studied in a curved channel at Dean numbers ranging from 50 to 200. The channel has a rectangular cross section of 1.27 cm by 50.1 cm giving an aspect ratio of 40 to 1. Flow is heated in a straight portion of the channel prior to the curved portion in order to obtain flow which is hydrodynamically and thermally fully developed. All baseline tests confirm techniques employed and qualify...

A study was conducted in an area off the Hellenic west coast to examine the spatial and time variability of various oceanic parameters, with special emphasis on those effecting ASW operations. Propagation loss runs were conducted using PE and RAYMODE models. The reactions of both models to different bottom morphology and sound speed profiles (seasons) were examined. Between the two models, the PE model was found to be closer to reality than RAYMODE. Results suggest that the application of these...

Efficient manpower utilization is essential to minimizing the cost, and a key element in that is the maintenance of the optimum balance between civilian and military manpower resources. Economic efficiency dictates that as the cost of military personnel begin to rise relative to the cost of direct hires, the Services would have an incentive to increase the use of direct hires, and vice versa. In our empirical analysis, results indicate that although DoD responded correctly to factor price...

This thesis compares the efficiency of a constraint branch-and-bound method against the conventional variable branch-and-bound method in solving set partitioning problems. Because of the difficulties encountered in writing the constraint branch-and-bound subroutine, it was necessary to solve each subproblem encountered from scratch. This is in contrast to the variable branching code which, when solving closely related subproblems, essentially starts from an advanced starting solution. Even...

The military, and specifically the Navy, is making a move toward the use of directed energy weapons as a tactical advantage over typical kinetic weapons. Directed energy weapons require different controls and delivery methods to deal with differences in interaction of the atmosphere and the laser, as compared to traditional kinetic weapons. This thesis looks at a Noise Variance Weighted Complex Exponential Reconstruction method, and compares with typical zonal and modal least squares methods,...

Investigations of scattered transient waveforms from conducting bodies have shown that it is possible to classify electromagnetic scatterers. The concept is based upon the natural resonance modes which are part of the scatterer response to an incident excitation. A new approach for describing natural resonance modes using recursive systems is introduced. A discrete auto- regressive moving-average (ARMA) type model for the case of the space-time wave equation is presented. This model results...

Considerations of real-time control problems for an Autonomous Underwater Vehicle (AUV) are addressed in this research. Among these problems is the ability to control the submersible given its highly nonlinear operation environment. In order to account for these variations, robust control techniques must be used. In particular, Variable Structure Control (VSC) with Doyle-Stein Observer has proven to produce optimal results while maintaining a high degree of robustness. This led to the...

An evaluation of the shielded stripline was conducted using an X-band waveguide to isolate a suspended strip transmission line. The analysis was conducted below the functional cutoff frequency of the X-band guide over a broad range of frequencies. The scattering coefficients were measured and used to compute the gap capacitances of the transmission line. The gap discontinuities were then used to confirm the theoretical assumed piequivalent circuit.

In this thesis a formal description technique, systems of communicating machines, is used to specify and analyze a token bus protocol. A simplified description of the protocol is given, and proofs of certain correctness properties presented. The analysis proves that the protocol is free from deadlocks and non executable transitions, and also that successful message transfer is guaranteed for a network with an arbitrary number of machines. A program written in an object oriented language, C++,...

A classical control system with a full-order observer is designed to stabilize the motions of towed vessels. The control method is transverse movement of the towline attachment point on the towed vessel. The linearized sway and yaw equations of motion are developed, leading to the control system design. The control system is tested using MATRIX. Results for a barge, mariner-class ship and a tanker are presented. Possible benefits of the implementation of such a system include improved fuel...

A two layer ocean mixed layer model is used to study the relationship between onset of freezing and mixed layer depth, wind forcing, surface buoyancy flux, and temperature and salinity changes between the two layers. Universal non- dimensional parameters for stability and surface forcing are derived and related to the maximum freezing rate. Analytic solutions to the model are found in terms of the universal parameters and the model turbulent mixing tuning constants. Sensitivity studies show the...

An important aspect of wireless communication is efficiency. Efficient network resource management and quality of service (QoS) are parameters that need to be achieved especially when considering network delays. The cooperative nature of unmanned ground vehicle (UGV) networks requires that bandwidth allocation be shared fairly between individual UGV nodes, depending on necessity. In this thesis, we study the problem of dynamic bandwidth provisioning in a UGV network. Specifically, we integrate...

While the application of a time-step approach in modeling C4ISR in Missile Defense Warfare (MDW) suffers inaccurate time estimation and relative slow speed, Discrete Event Simulation (DES) can elegantly satisfy these shortages. However, current DES frameworks typically rely on detailed efforts in event analysis for numerous replications before software modification of the simulation scenario can be meaningful. Such approaches have limited adaptability, especially regarding flexibility of...
